Dielectric properties of hydroxyapatite based Strontium doped powders produced by hydrothermal method
Abstract
Hydroxyapatite, one of the bioceramic materials, is one of the most biologically adaptable materials to the human body with the formula Ca10(PO4)6(OH)2, which is similar to the structure of bone and tooth. For this HA is a biomaterial, HA was used in the study and pure HA and HA-based 1%, 5% and 10% Sr-doped nanopowders were produced and their FTIR-ATR, SEM and dielectric properties were examined. After FTIR-ATR analyzes taken from the produced powders confirmed that doping had occurred, the powders were turned into pellets and their dielectric properties were examined. It was determined that the materials were polarized in the frequency-dependent real and imaginary dielectric curves. The cole-cole and B(S)-G(S) curves examined later confirmed this situation. The change of the additive amount was examined by keeping the 10h reaction time and 180 oC temperature value constant. It has been observed that the polarization properties of the materials change depending on the amount of additives, therefore the produced materials can be used in biomedical applications.
